Audio stops after startBluetoothSco in Android 11

Audio stops after startBluetoothSco in Android 11 - java

The moment I bind an Android 11 device using startBluetoothSco I loose audio. It works fine till Android 10
Sample code I tried with below.
Audio works as it should when i do not bind using startBluetoothSco.
I also added queries tag in AndroidManifest.xml
android:name="android.intent.action.TTS_SERVICE"
That didn't help either!

I was able to figure it out. I did try it once before, but didn't work then. Not sure why.
Document reference AudioManager#startBluetoothSco

ttsBundle.putInt(TextToSpeech.Engine.KEY_PARAM_STREAM, AudioManager.STREAM_VOICE_CALL);
textToSpeech.speak(editText.getText().toString(), TextToSpeech.QUEUE_FLUSH, ttsBundle, null);

user.getUsername() crashes the application

I have recently created a chatting application, which gets crash due to these lines :-
reference.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot dataSnapshot) {
User user = dataSnapshot.getValue(User.class);
t_username.setText(user.getUsername());
if (user.getImageURL().equals("No image")){
profile_image.setImageResource(R.drawable.profile_img);
} else {
//change this
Glide.with(getApplicationContext()).load(user.getImageURL()).into(profile_image);
}
}
#Override
public void onCancelled(#NonNull DatabaseError databaseError) {
}
});
I don't understand why this crashes my application.

My Problems that not solved are
The app is not working when I add an onItemclicklistener to the list view.
bluetooth search result is filling with the same device name.
I cannot access the buttons after viewing pairing devices and
scanned devices(it seems like that the same layout is popping to screen).
Anyone please help me to solve these issues.
Thanks in advance.

You can just do like this -
mListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getApplicationContext(), " ITEM CLICKED POSITION = "+String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});

You can add OnItemClickListener like this
mListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) { {
Toast.makeText(getApplicationContext(),String.valueOf(arg2), Toast.LENGTH_LONG).show();
}
});`

look at this code it contain how you set the list view listener with detect the clicked row and getting sub view in that row
ListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
View row= adapter.getView(position, view, parent);
CheckBox box=(CheckBox) row.findViewById(R.id.checkBox1);
box.performClick();
}
});
adapter is your list view adapter
hope it help
